Modeling and Simulating Causal Dependencies on Process-aware Information Systems from a Cost Perspective

Providing effective IT support for business processes has become crucial for enterprises to stay competitive in their market. Business processes must be defined, implemented, enacted, monitored, and continuously adapted to changing situations. Process life cycle support and continuous process improvement become critical success factors in contemporary and future enterprise computing. In this context, process-aware information systems (PAISs) adopt a key role. Thereby, organization-specific and generic process support systems are distinguished. In the former case, the PAIS is build "from scratch" and incorporates organization-specific information about the structure and processes to be supported. In the latter case, the PAIS does not contain any information about the structure and processes of a particular organization. Instead, an organization needs to configure the PAIS by specifying processes, organizational entities, and business objects. To enable the realization of PAISs, numerous process support paradigms, process modeling standards, and business process management tools have been introduced. The application of these approaches in PAIS engineering projects is not only influenced by technological, but also by organizational and project-specific factors. Between these factors there exist numerous causal dependencies, which, in turn, often lead to complex and unexpected effects in PAIS engineering projects. In particular, the costs of PAIS engineering projects are significantly influenced by these causal dependencies. What is therefore needed is a comprehensive approach enabling PAIS engineers to systematically investigate these causal dependencies as well as their impact on the costs of PAIS engineering projects. Existing economic-driven IT evaluation and software cost estimation approaches, however, are unable to take into account causal dependencies and resulting effects. In response, this thesis introduces the EcoPOST framework. This framework utilizes evaluation models to describe the interplay of technological, organizational, and project-specific evaluation factors, and simulation concepts to unfold the dynamic behavior of PAIS engineering projects. In this context, the EcoPOST framework also supports the reuse of evaluation models based on a library of generic, predefined evaluation patterns and also provides governing guidelines (e.g., model design guidelines) which enhance the transfer of the EcoPOST framework into practice. Tool support is available as well. Finally, we present the results of two online surveys, three case studies, and one controlled software experiment. Based on these empirical and experimental research activities, we are able to validate evaluation concepts underlying the EcoPOST framework and additionally demonstrate its practical applicability

Understanding the Costs of Business Process Management Technology

Providing effective IT support for business processes has become crucial for enterprises to stay competitive in their market. Business processes must be defined, configured, implemented, enacted, monitored and continuously adapted to changing situations. Process life cycle support and continuous process improvement have therefore become critical success factors in enterprise computing. In response to this need, a variety of process support paradigms, process specification standards, process management tools, and supporting methods have emerged. Summarized under the term Business Process Management (BPM), they have become a success-critical instrument for improving overall business performance. However, introducing BPM approaches in enterprises is associated with significant costs. Though existing economic-driven IT evaluation and software cost estimation approaches have received considerable attention during the last decades, it is difficult to apply them to BPM projects. In particular, they are unable to take into account the dynamic evolution of BPM projects caused by the numerous technological, organizational and project-specific factors influencing them. The latter, in turn, often lead to complex and unexpected cost effects in BPM projects making even rough cost estimations a challenge. What is needed is a comprehensive approach enabling BPM professionals to systematically investigate the costs of BPM projects. This chapter takes a look at both known and often unknown cost factors in BPM projects, shortly discusses existing IT evaluation and software cost estimation approaches with respect to their suitability for BPM projects, and finally introduces the EcoPOST framework. EcoPOST utilizes evaluation models to describe the interplay of technological, organizational, and project-specific BPM cost factors as well as simulation concepts to unfold the dynamic behavior and costs of BPM projects

Evaluation Patterns for Analyzing the Costs of Enterprise Information Systems

Introducing enterprise information systems (EIS) is usually associated with high costs. It is therefore crucial to understand those factors that determine or influence these costs. Existing cost analysis methods are difficult to apply. Particularly, these methods are unable to cope with the dynamic interactions of the many technological, organizational and project-driven cost factors, which specifically arise in the context of EIS. Picking up this problem, in previous work we introduced the EcoPOST framework to investigate the complex cost structures of EIS engineering projects through qualitative cost evaluation models. This paper extends this framework and introduces a pattern-based approach enabling the reuse of EcoPOST evaluation models. Our patterns do not only simplify the design of EcoPOST evaluation models, but also improve the quality and comparability of cost evaluations. Therewith, we further strengthen our EcoPOST framework as an important tool supporting EIS engineers in gaining a better understanding of those factors that determine the costs of EIS engineering projects

On Handling Process Information: Results from Case Studies and a Survey

An increasing data overload makes it difficult to provide the needed information to knowledge-workers and decision-makers in today's process-oriented enterprises. The main problem is to identify the information being relevant in a given process context. Moreover, there are new ways of collaboration in the context of distributed processes (e.g., automotive engineering, patient treatment). The goal is to provide the right process information, in the right format and granularity, at the right place, at the right point in time to the right people. Picking up this goal, enterprises crave for an intelligent and process-oriented information logistics. In this paper we investigate fundamental issues enabling such information logistics based on two exploratory case studies in the automotive and the clinical domain. Additionally, we present results of an online survey with 219 participants supporting our case study findings. Our research does not only reveal different types of process information, but also allows for the derivation of factors determining its relevance. Understanding these factors, in turn, is a fundamental prerequisite to realize effective process-oriented information logistics

Towards Process-oriented Information Logistics: Why Quality Dimensions of Process Information Matter

An increasing data overload makes it difficult to deliver needed information to knowledge-workers and decision-makers in process-oriented enterprises. The main problem is to identify information being relevant for process participants and their activities. To cope with this challenge, enterprises crave for an intelligent and process-oriented information logistics. The major challenge is to provide the right process information in the right format and level of granularity at the right place and accurate point in time to the right actors. When realizing such process-oriented information logistics it becomes crucial to take into account quality dimensions of process information (e.g., completeness, topicality, punctuality). Reason is that these dimensions determine process information quality and thus also the overall relevance of process information for a particular process participant and his activities. This paper picks up this issue and analyzes different quality dimensions of process information and their impact on process-oriented information logistics

Navigating in Complex Business Processes

In order to provide information needed in knowledge-intense business processes, large companies often establish intranet portals, which enable access to their process handbook. Especially, for large business processes comprising hundreds or thousands of process steps, these portals can help to avoid time-consuming access to paper-based process documentation. However, business processes are usually presented in a rather static manner within these portals, e.g., as simple drawings or textual descriptions. Companies therefore require new ways of making large processes and process-related information better explorable for end-users. This paper picks up this issue and presents a formal navigation framework based on linear algebra for navigating in large business processes

Unleashing the Effectiveness of Process-oriented Information Systems: Problem Analysis, Critical Success Factors and Implications

Process-oriented information systems (IS) aim at the computerized support of business processes. So far, contemporary IS have often fail to meet this goal. To better understand this drawback, to systematically identify its rationales, and to derive critical success factors for business process support, we conducted three empirical studies: an exploratory case study in the automotive domain, an online survey among 79 IT professionals, and another online survey among 70 business process management (BPM) experts. This paper summarizes the findings of these studies, puts them in relation with each other, and uses them to show that ”process-orientation” is scarce and ”process-awareness” is needed in IS engineering

Towards Process-Aware Enterprise Software Environments - A Framework

To stay competitive at the market companies must tightly interlink their software systems in a process-oriented manner. While the business process paradigm has been widely accepted in practice, the majority of current software applications are still not yet implemented in a process-oriented way. But even if, process logic is hard-wired in the application code leading to inflexible and rigid software systems that do not reflect business needs. In such a scenario the quick adaptation of the software systems to changed business processes is almost impossible. Therefore, many software systems are already out of date at the time they are introduced into practice, and they generate high maintenance costs in the following. Due to this unsatisfactory business process support a software system’s return on investment is often low. By contrast technologies which enable the realization of process-aware enterprise software environments will significantly contribute to improve the added value of IT to a company’s business. In this paper we characterize process-aware enterprise software environments, describe benefits and present a conceptual framework outlining our theses

Navigating in Process Model Collections: A new Approach Inspired by Google Earth

In complex business environments, business processes (e.g., engineering processes in the automobile industry) may comprise hundreds up to thousands of process steps. Though typically captured in a process model (or a collection of process models), these processes are presented to process participants in a rather static manner, e.g., as simple drawings. However, to effectively support process enactment and to link processes with relevant information,enterprises crave for new ways of visualizing processes and for interacting with them. In particular, process models must be provided in an interactive, more dynamic manner, i.e., they must be both "experiencable" and user-adequate from the perspective of the user. In this paper, we introduce a new process navigation concept for querying process model collections. Specically, we pick up an existing navigation concept for complex information spaces, namely Google Earth, and apply it to business processes. Thereby, we distinguish between geographical and semantic zoom functions, introduce different process views and filter mechanisms, and discuss options to manually configure needed process visualizations

Towards an Evaluation Framework for Business Process Integration and Management

Process-awareness in enterprise computing is a must in order to adequately support business processes. Particularly the interoperability of the (process-oriented) business information systems and the management of a company’s process map are difficult to handle. Process-oriented approaches (like workflow systems and enterprise application integration tools) offer promising perspectives in this respect. However, a major problem for project managers is the accomplishment of economic-oriented assessments of such approaches. Currently, there exists no suitable evaluation framework. This position paper discusses important issues related to the introduction of such a framework. Doing so, we distinguish two evaluation areas: Business Process Integration and Business Process Management. While the former operates at the technical level of process and application integration, the latter addresses organizational process topics. Starting from those two perspectives we describe benefits, evaluation criteria and metrics that are relevant to set up an evaluation framework
